I was about to splash out on K2 when I decided to have a quick look at the NI forum. Boy there seem to be a shedload of unhappy K2 users! Principal complaint appears to be the really high load on CPU to the point of it being unusable with anything more than a small number of instruments loaded. I was really surprised about this, not least because most K2 users posting to this forum seem really pleased with it. I'm not really interested in using it for anything other than a sample library player but would be interested in having views on the current state of play. Why the different perceptions of this product?
